Comment 21 for bug 1532746

I can confirm WiFi issues on Windows, but turning off energy saving fixed
the problem (before this WiFi only worked correctly when the charger was
plugged in). On Ubuntu 14 I also experienced the same problem, but once I
updated to Ubuntu 15 the problem went away. It seems that the Linux kernel
used by Ubuntu 14 didn't support the wireless adapter.
